This series of patch convert txt file (xlnx,zynqmp-reset.txt) to yaml
(xlnx,zynqmp-reset.yaml) DT schema format and adding reset-controller
property to the firmware dt-binding.
---
Note:
The 1/2 patch introduced a warning related to the dt binding check,
which was subsequently fixed in the 2/2 patch. This warning is a
conversion warning due to a dependency on firmware dt binding.

The reset controller is responsible for managing both device-level resets
and individual PMC (Power Management Controller) block resets.
To facilitate this functionality reset-controller property is added to the
firmware device tree binding.

This dt_binding warning is known to us and is captured in commit description notes and to resolve it, we need to apply 2/2.
I want to take DT maintainer opinion if we should keep the fix in 2/2 or merge it in 1/2.

So your patchset has broken bisectability. You need to fix it. If the
warning was known, then I am surprised that you sent broken patchset.

Just avoid the warning. Anyway you need only one complete example, right?

The first patch is conversion from txt yaml without any additional changes
because in past we heart that we shouldn't really do other things in it. That's
why 2 patches where made. No really issue to squashed them together.

We always shared feedback that conversion should do only conversion, but
a correct one. Conversion cannot introduce errors or warnings in the
bindings. It can introduce warnings in DTS, but not in the bindings.
This was also communicated several times.
If pure-conversion results in non-bisectable patchset then:
1. either conversion should come with changes,
2. or conversion is done a bit wrong or could be done differently like
here. You really do not need unrelated pieces of DTS in reset controller
code. Drop them.
